Abstract

The invention discloses a conical arc plate drilling clamp tool, relates to a drilling clamp tool for plate parts, and aims to solve the problem that the conventional conical arc plate drilling clamp tool cannot simultaneously meet the machining precision of various holes of the conical arc plate. An acute angle formed between a midperpendicular of an upper body and a bottom plane of the base is 83 degrees; a positioning pin is simply arranged in a pin mounting hole and is arranged in a positioning pin cylinder; a spring sleeve is arranged on the positioning pin; a stepped rotating shaft is arranged in a shaft mounting hole; a small diameter end of the stepped rotating shaft is connected with a central hole of a cone; an outer conical surface of the cone is consistent with an inner surface of the conical arc plate; a notch subjected to profile modeling of the conical arc plate is formed on the lower surface of an arc plate drill jig; a through hole is formed on the arc plate drill jig; a positioning groove is formed on an end face which is close to the upper body, of the cone; the arc plate drill jig is buckled on the outer conical surface of the cone; the conical arc plate is inserted into the notch; and a positioning column subjected to profile modeling on the positioning pin is inserted into the positioning groove. The conical arc plate drilling clamp tool is used for a conical arc plate drilling process.

Description

technical field [0001] The invention relates to a drilling fixture tooling for plate parts, which belongs to the technical field of mechanical processing. Background technique [0002] Conical curved plate (such as figure 1 , the thickness of the plate is 3mm) each connecting hole of the part is drilled before connecting with a certain part in the assembly, this processing method can only meet the production requirements of small batches or single assembly. In addition, the conical arc-shaped plate needs to be disassembled frequently in the process of debugging and measurement and control. The connection between the cover plate and the transition cabin is only for processing, which does not meet the size requirements marked on the product drawing, and cannot guarantee the interchangeability of various product parts. In mass production, if you do not mark them one by one, once they are mixed, it is easy to cause confusion that cannot be assembled; because it is equipped with...
